Development of artificial extracellular matrices based on multifunctional 3D scaffolds for cancer (immuno)therapy

We develop different 3D synthetic and hybrid hydrogels to imitate extracellular matrices of different healthy and diseased tissues, especially from the immune system, with the objectives to 1) elucidate cancer- and immunotherapy-related cellular mechanisms, 2) improve immune cell cultures, and 3) develop novel patient-derived organoids, to have a positive influence on cancer (immuno)therapy and related disciplines.

Design and fabrication of multifunctional 2D nanostructured surfaces for initiating immune cell responses related to cancer immunotherapy

We develop different functional 2D nanostructured surfaces on rigid substrates and hydrogels based on the block copolymer micellar lithography technique. These functional nanostructures are used to study the influence of different biomolecules and their cross-talk on (T) cell behavior.
